Abstract

This paper reports the results of an experimental study investigating the impact and the one-year sustainability of the effects of the Dynamic Integrated Approach (DIA) to teacher professional development. Teaching skills of the participating teachers and their student achievement in mathematics were measured at the beginning and at the end of the interventions. The DIA had an impact on improving teaching skills and student achievement. A follow-up measurement of teaching skills, one year after the end of the interventions, revealed no further improvement or declination. Implications are drawn and suggestions for further research are provided.
